On approach, both main gears remained jammed in their wheel well and only the nose gear was down and locked. The airplane landed on its belly and slid for few dozen meters before coming to rest. All 60 occupants escaped uninjured while the aircraft was damaged beyond repair.

Circumstances:
The four engine aircraft was performing a schedule service MS771 from Cairo to Zurich with an intermediate stop in Geneva, carrying 174 passengers and a crew of 10. Following an uneventful flight from Cairo-Intl, the crew was cleared to descent for an ILS approach to Geneva-Cointrin Airport runway 23. On short final, the captain failed to realize his altitude was insufficient when the right main gear struck an ILS antenna. Few seconds later, the airplane landed 35 meters short of runway threshold. While contacting the concrete runway, all three landing gear were torn off. The airplane slid on its belly for about 900 meters then made a left turn and lost its right wing before coming to rest. A fire erupted on the right side of the airplane but was quickly extinguished. All 184 occupants were evacuated, two passengers were seriously injured during the evacuation. The aircraft was destroyed.
Probable cause:
The accident was the consequence of the followings:
- Lack of decision on part of the pilot-in-command (captain) who failed to initiate a go-around procedure following a wrong approach configuration after the aircraft passed below 1,000 feet or at least after passing over the outer marker,
- Insufficient work coordination in the cockpit, after the crew failed to follow the approach checklist and all instructions relative to approach and landing controls, lack of a clear distribution of tasks as well as surveillance and mutual assistance (doublecheck / crosscheck),
- Stubbornness to land once the ground in sight despite a wrong approach configuration (airbrakes deployed) with an excessive rate of descent.
The following contributing factors were reported:
- Omission of a correct approach and landing planing,
- Late increase of engine power during the last portion of the approach,
- A possible inadvertent deployment of the interior airbrakes shortly before impact.

Circumstances:
Following an uneventful flight from Singapore via Kuala Lumpur, the crew started the descent to Bombay-Santa Cruz Airport by night. The visibility was poor due to the combination of fog and night. On final, the captain reduced engine power at minimum, causing the aircraft to adopt an excessive rate of descent. Twelve seconds later, the aircraft landed hard on runway 27. Main wheel wells and tires were damaged upon impact and several alarms sounded in the cockpit. The captain increased engine power and decided to initiate a go-around. The airplane continued for few hundred meters but rolled on the right shoulder of the runway before takeoff. After liftoff, the stick shaker activated as the aircraft was in stall conditions. It lost height then crashed near the runway end, bursting into flames. Two crew members and 15 passengers were killed, 45 other occupants were injured and 49 others escaped uninjured.
Probable cause:
Wrong approach configuration on part of the crew who led the aircraft adopt an excessive rate of descent during the last segment.

Failure of the right main gear upon touchdown due to shock absorbing asymmetry. The following contributing factors were reported:
- Landing gear: main gear - struts, attachments,
- Fatigue fracture,
- Right main gear truck beam, PN 50-9725-2 failed,

Circumstances:
After takeoff from Tokyo-Narita Airport while on a cargo flight to Bangkok, the crew reported technical problems with the engine n°3 after the n°6 carbon seal was worn, causing a loss of lubrication. The crew was cleared to return for an emergency landing but weather conditions were marginal and the visibility was limited. Following an approach to runway 16, the airplane was too high and passed over the threshold at a height of 500 feet. The crew continued the descent and the aircraft landed 1,700 meters past the runway threshold and bounced. After reverse thrust was applied on engine n°1, 2 and 4, the airplane veered off runway and struck a manhole, causing the nose gear to collapse. The airplane came to rest and was damaged beyond repair while all three crew members were uninjured. At the time of the accident, wind was from 210 to 350°, 11 knots gusting to 34 knots, visibility 2,200 meters, RVR 900 meters for runway 16 with heavy rain falls and fog.
Probable cause:
The accident was the consequence of the combination of the following factors:
- Unfavorable weather conditions,
- Wrong runway selection according to wind component and weather,
- Wrong approach configuration,
- The crew failed to initiate a go-around,
- The crew misunderstood ATC instructions.
